Improved peed-water heater



@niet eine Letters Patent No. 97,371, dated November 30, 1869.

IMPROVED FEED-WATER HEATER.

The Schedule referred to in these Letters Patent and making part of the same.

To 'all whom it 'may concern .seription thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot this specilicaton. v

The object of this invention is to provide feed-water heaters for steam-boilers, having greater heating-capacity, and adapted also for filtering the water, and to have great condensing-capacity for returning the steam as teed-water,for use when the feed-water is not always abundant, and particularly adapted for portable and traction-engines. l

The drawing represents a side elevation ofa heater, constructed according to my improvements, some parts being broken out.

A and B represent upper and lower heater heating-vessel, connected to the exhaust-pipe C of' the engine, for the reception `of the steam, and into which the supply-water is fed by the pipes I.) E. 4

G H represents the exhaust-pipes, for the surplus steam to pass oii. From the lower heater A it passes into the upper one, through the pipe These pipes I provide with elbows I, so arranged as to take the steam from directly under the water-supply pipes D E, when the steam must encounter the iuilowing water in the manner to have the best effects in` condensing the steam.

Between these heaters, A B, l introduce any number ot' filtering-vessels K, provided with hay or other iilteringsubstance, through which the heated water from the upper heater B is caused to pass down through the first and 'up through the second, and so on through the series, and into the heater below.

This cools the water to a great extent while filtering it, thewater thus cooled passing into the heater below, where it again encounters the steam, condenses it here to a great extent, saving it for use again, and is again greatly heated previous to entcringtl'le boil/er.

From the lower heater the water flows to the feedpunip, through pipe L.

By this improved device .I am enabled to accomplish three important obj ect-s in a great. measure, working a considerable economy in the operation of Vsteaulengines and boilers, especially in the matter of filtering' the water, whereby the pipes, boiler, and valves 4are kept clean, and the danger oi' burning them or exploding the boiler avoided, and an economy of fuel effected inthe better application of' the heat.

Having thus described my invention,

\Vhat I claim as new, and desire to secure by Let-l ters Patent, isv The combination of two heaters, A and B, and any number ot' filtering-vessels, K, when connected and arranged, substantially in the manne;l specified.
